Question

(V5+V3)^2-2V15Вычислить значение выражения (V-корень)

Answer 1

(√5+√3)²-2√15=(√5)²+2√5·√3+(√3)²-2√15=5+2√15+3-2√15=8

Answer 2

To calculate the value of the expression $(V_5 + V_3)^2 - 2V_{15}$, we need to find the square root of $V_{15}$ and then substitute the values of $V_5$ and $V_3$.

First, let's find the square root of $V_{15}$:

$\sqrt{V_{15}}$

Now, we need to substitute the values for $V_5$ and $V_3$. However, you didn't provide the values of $V_5$ and $V_3$ in your question. The "V-корень" notation is not standard mathematical notation, and I'm unsure what you mean by it. If "V-корень" refers to the square root, then we can proceed as follows:

Let's assume $V_5 = a$ and $V_3 = b$. Then the expression becomes:

$(a + b)^2 - 2\sqrt{V_{15}}$

Without knowing the specific values of $a$ and $b$ (i.e., $V_5$ and $V_3$), we cannot calculate the exact numerical value of the expression. If you provide the values for $V_5$ and $V_3$, I'd be happy to help you with the calculations.
